The Sir John Herschel Collection
The preparation of the print Calendar of the Correspondence of Sir John Herschel (Michael J. Crowe ed., David R. Dyck and James J. Kevin assoc. eds, Cambridge, England: Cambridge Univ. Press, 1998, viii + 828 pp) which was funded by the National Science Foundation, took ten years. It was accomplished by a team of seventeen professors, visiting scholars, graduate students, advanced undergraduates, and staff working at the University of Notre Dame.
The first online version of Calendar was created in 2009 by Dr Marvin Bolt and Steven Lucy, working at the Webster Institute of the Adler Planetarium, and it is that data that has now been reformatted for incorporation into Ɛpsilon.
Further information about Herschel, his correspondence, and the editorial method is available online here: http://historydb.adlerplanetarium.org/herschel/?p=intro
No texts of Herschel’s letters are currently available through Ɛpsilon.

Will be out of town for next [R.S.L.?] council meeting. Comments on glass subcommittee report.
Acknowledging the letter of 25 Nov. informing GM that he has been elected to the R.S.L. Will attend at the earliest opportunity to be admitted.
Thanks for the works. How can he send some for the R.S.L. and Astronomical Society?
Thanks for the kind reception afforded him at Slough. Sends a copy of [J. H.?] Schröder's paper on the discoveries of William Herschel. Also sends some observations of the late solar eclipse made in Holland.
Sending their account for J. J. Littrow's astronomical clock, now packed and shipped.
Is sailing for Buenos Ayres in a few days' time. Would like to thank JH for his kindness; would also like to see him, if convenient, before he departs.
May choose one of each of the new specimens of Boracite crystals; the remainder send to C. D. E. König at the British Museum, together with the enclosed letter. Is now recovering from his sickness.
Sorry they will not have a sight of the Herschels before they depart. Has arranged for the camera to be delivered to Kensington. The Murchisons are off to Dover tomorrow.
Has received the regulations of the Astronomical Society of London—a great encouragement to astronomers. Has made observations on the orbit of the comet. Has sent two memoirs to T. M. Brisbane.
Introducing his friend Mr. De Lavigne, who is visiting England. Mentioned him in his memoir on the Measure of the Arc.... Gives news of his own astronomical work. Edward Sabine arrives at the end of the month. Has obtained remarkable results with his two pendulums.
Has received the actinometer safely by the hand of Mr. De Lavigne, also the instructions. Hopes to use it in the Alps, and will send some observations. De Lavigne was enchanted with England.
Has just returned from the Alps, where he worked on the glacier at Chamouny and in the St. Bernard. Comments on his work and on the work of the actinometer. Regrets to hear of the death of Mrs. Babbage.
Outlines the difficulties he has had to return JH's actinometer. Gives details of his observations in the Alps. Comments on the chronometer used.
Sending observations of his barometrical observations made during the summer at Chamouny. Comments on them and the work of [Alfred?] Gautier.
Sends copies of a paper to JH and D. F. J. Arago on a chemical experiment being conducted at the Institute of France. Asks JH to present it to the R.S.L.
Apologizes for the long delay in writing of JH's election into the Danish Royal Academy of Sciences. HO is carrying on experiments with chlorine gas and metals.
Honored on being elected Foreign Member of the Astronomical Society of London. Finds that the comet he observed in January had already been seen by J. N. Nicollet and J. L. Pons. Saw the remarkable appearance on the dark part of the moon noticed by Henry Kater. Thinks Kater's theory is wrong. Will soon be bringing out a paper on the moon's volcanoes.
Discusses comet observations, together with variations from different observers. HO offers some historical fragments about the planet Venus, and about the Lilienthal telescope.
Comments on the observations JH has made with his 20-foot telescope, especially nebulae. HO provides some of his own observational data of Comet Encke.
